Allow node/edge to show 5+ indicators at once

[keyserj]

Describe your issue

If selecting a node by clicking on its border is good enough, we don't need the Details Indicator for selecting the node. In which case, it'd be nice if it could just be used to show if a node has notes (maybe rename to "Notes Indicator" too), and it could go on the bottom right of a node, where other Content Indicators go. But there isn't enough space for a fifth indicator, if all of them are indicating at once:

Solution you'd like

Unrefined notes:

• create edge by click-drag on top/bottom of node to bottom/top of another node, like this example except top/bottom half distinctions
  • probably could give node a draggable event that checks if we're on the top half of pixels or bottom half, and starts a connection event based on that
• use a different indicator for hidden neighbors
  • like a heavy shadow on the top vs bottom (jk, this doesn't allow hover/click for viewing the hidden nodes)
  • maybe a second card border on top vs bottom like Kialo does
• ... but the badges will still look awkward for edges?
  • I guess if edges don't have a border, they can keep expanding outwards

In #648, renamed details indicator to notes indicator, moved it to a badge, and removed the edge label border unless it's being highlighted.

This should lower the priority of this issue, but the notes indicator was shoehorned into the Status Indicators because there wasn't enough space in the Content Indicators section. It'd still be nice to allow 5+ indicators in the Content Indicators section, since the notes indicator is more of a Content Indicator.
